OUTLET BOX.

Application med-m a2, 1925. Serial a 45,145.

My invention relates-to outlet boxes and has for one-of its objects to provide simple and efficient means for securing the box in position in a wall and at the same time bracing the wall itself, so as to avoid any danger of having the plaster cracked or broken at those portions adjacent to the box. According to the design illustrated the supporting means are adapted to cooperate with a wall'composed of lath and plaster and means are provided for engaging both the.

interrupted and the uninterrupted la.ths. It is my purpose to provide means for stifi'enin the wall structure b bracing the interrupte laths and enabling t rem to take advantage of the stillness of the adjacent uninterrupted laths. Another object is to rovide an advantageous form of supporting bracket for securing the box to the adjacent stud or up ri ht.

accomplish my objects by the construction illustrated in the accompanying drawings in which Figure 1 is a perspective view showing my device mounted in position in a wall to which the plaster has not yet been applied.

igure 2 is a fragmentary perspective view showing the manner of attaching the stud bracket to one side of the box.

Figure 3 is a plan section of the box showing it mounted in position in the finished wall to which plaster has been a plied.

Like numerals denote li e parts throughout the several views.

In my device the boxitself is of ordinary form, being of sheet metal open at the front and closed at the sides. The front edges of the box in practice are intended to come flush with the outer or front surface of the plaster when the wall is complete. In the form illustrated the upper and lower sides 10 and 12 respectively are provided with apertured lugs 14 for securing the box to the uninterrupted laths 16, which pass adjacent to the upper and lower sides of the box and are secured at the ends to the studding 18 by nails 20 or other appropriate fastening means.

the front of the stud and an end ortion 28 extending at right angles to the ront portion and adapted to come between lugs 30 struck from the metal forming the side of the box as shown in perspective in Figure 2. Vhile the design may be greatly varied, lugs 32 may be formed at the extremity of the end portion for engaging the sides of the lugs 30.

After the parts are assembled the lugs 30 may be peened over onto the end portion 28 to rigidly hold the parts assembled, as 111115.- trated in Fi ures 1 and 3. The main body of thebracket has rows of apertures 34 for rcceiving nails 36 or other fastenin devices for securing the bracket to the stu The opposite side wall 24 has fastened to it a brace or steadying elementhavin a main body 38 adapted to contact thedsi e of the box and a flange 40 arranged at right angles to it in a vertical lane and located in position to engage the back of the la'ths: in other words, the front surface of flange 40 is as far back of the front edge of the box as the thickness of a lath plus the thickness of the Iplroposed plaster layer 41. The flange 40 has ngers 42 projecting above and below the box to engage the uninterrupted laths 16 as well as the interrupted laths 44 which terminate at the side of the box. It is desirable, also, to form vertical projections 46 at the forward portion of the main body of the brace for engaging the front of the uninterrupted laths 16. Thus in the best form of the device the uninterrupted laths will pass between two vertically arran ed fingers 42, 46 extendin above and be ow the top and bottom of-the x respectively.

In practice the parts are assembled as illustrated in Fi ures 1 and 3. The box is secured at one side y nailing the bracket 26 to the studding. The opposite side, top and bottom, are braced by the e ement 38, the lateral flange 40 whereof engages the back of the interrupted laths 44 and the fingers 42, 46 whereof pass to either side of the uninterrupted laths 16. After the parts are thus assembled the plaster 41 is ap lied to the lath to finish the wall in the usua manner. This gives a most the =rigidity' ofi the uninterrupted"dathsrtoit brace themselves through the ageney ofithm lateral flange 40, which engages the back-of the laths both withinfand beyond the vertical confines of the box. It'will be*evident;-there= f* fore, that my invention provldesmeans of" very simple form for not only holdingth box rigidly'in position but alsobraeingigtheg wall and making a unitary structure 0mm those portions adjacent to the boxythus'elim-w inatingithe danger of cracking-the plasterainw thevicinity of the box.
